A morning of very low wind gave us the perfect opportunity to survey the sewage lagoons. Chiffchaff was leading species with 17 and only two of these adults, both females with brood patch code 5 (feathering over) and showing very nice examples of advancing primary moult now the breeding season is finished.
Similarly other adult migrant warblers captured were also commencing moult, although Sedge and Reed Warblers only begin body moult in the UK, doing their flight feathers much later in the year.
The juveniles are also on their way with over half starting post juvenile moult and several laying down fat in preparation for the migration south.
